10 Unexpected Window Sash Repairs Tips

Window Sash Repairs
Window sashes need to be regularly checked for mold, mildew and damage. You can reduce future repair costs by catching these issues early, before they become out of control.
The sash is an internal frame that can move vertically up and down in windows that open. This article will demonstrate how to do a variety of simple repairs to the sash.
Weather Stripping
Wood window sashes give the classic look to your home and, when properly maintained, can last for years. They may, however, become damaged or degraded with time, due to exposure and normal wear and tear. However, sash repair experts can restore your windows to their original condition and keep them looking great for a longer period of time than replacement windows.
The first step for repair sash window damage is to fix weather stripping, which can be found on both the sash as well as the frame. If it's worn or loose, out, it could cause drafts and other issues. Start by identifying the brand of window and the glass manufacturer's date (etched on the corner of the glass or the aluminum spacers between panes). Remove the sash, and mark its width and height so that you can get new weather stripping that is compatible with the original.
Then, remove the sash and place it on a table so you can access all four sides. If your sash was double-hung, you must remove the weights with their ropes that should be buried in the jamb lining. Once you've removed the sash and the weights, use a utility knife to cut off the old weather stripping at the corners, then remove it by hand or using a putty knife.
After the sash has been cleared, you can replace parting stops. These are long pieces that separate the sashes. Pam likes to replace them with standard 1/2-inch-by 3/4-inch window trim from the lumberyard, but you could also use scrap wood.
After removing the parting stop and cutting it to length and then apply a thin layer of glazing compound over the bottom of the sash. Smooth it out using your putty knife and let it dry for a minimum of a day. After it has fully dried and dried, apply a second coat of acrylic latex paint. This coating will protect the putty and give your sash a new appearance.
Sash Hardware
The hardware that holds window sashes is prone to wearing out from time and usage, and the result can be a door or window that won't open or close easily. The good news is that repairing and replacing this hardware is usually very simple and cost-effective. If a sash is difficult to operate you can try spraying some grease into the jamb channel then slide it open to see if it fixes the problem. If the issue continues, it is most likely that the sash balance is off. You'll need to take off the window sash in order to access the hardware.
The ideal situation is for window sashes to move open and shut without effort, however, this can be difficult if the weights become worn or if the sash that joins rail isn't properly coated. This issue can be due to various reasons, including the lack of maintenance or an unmatched weight rating.
If the hinge arms on a window begin to sag this could cause the sash to drag and then hit the frame in the opposite corner (Photo 1). To fix this issue, first make sure the sash is firmly seated in the opening of the frame and then take it out of the window. If the sash is fixed to the hinge arm, unbolt the hinge and replace it. (Photo 2). Next, install the new sash (Photo 3).
Due to hinges that are sagging, and a general lack in energy efficiency, windows that are old particularly those in older homes, can be difficult to open and close. In most instances, a few minor repairs can transform these windows into smooth operators for the first time and save the homeowner money on energy costs.
It is important to have the tools needed before you begin. Begin by marking the position of the hinge channel on the frame with pencil (Photo 1). This will help you get the channel back into place correctly when you're finished. Remove the sash, and then remove the hardware including the parting beads (Photo 2) and the chains or cords that secure it. Soften any hardened putty with the help of a heat gun set at medium and equipped with a shield to block the nozzle. Remove the old sash and place it in a bag that is labeled.
Sash Weights
Sash weights are able to be replaced to enhance the efficiency of your window sash and reduce the cost of energy. Sash weights are heavy, lead or iron cylinders enclosed inside a hidden compartment and connected to the movable sash by rope. These weights function as counterbalances, which allows you to open and close the window without the need for mechanical or electrical devices. If they fail, sashweights are usually ignored or disabled by homeowners.
A weight from a sash that fell out of the cavity is difficult to recover, so you will want to locate a new one that fits properly. You will also require a new piece of string, a length sash cord and some sash pulleys that will tie the new sash weights to the sash cord.
Older wood windows are joined by mortise and tenon joints. The wood pegs that hold the parts together can be removed by the use of a pin punch and hammer. The majority of these pegs are big on one side, but smaller on the other. It is essential to first remove the smaller diameter sides. Later sashes used glue instead of pins. They can be cut by using a knife and a mallet.
Once the sash has been released, you can remove the stops on the sash and get access to the pockets for weights. This is usually done via an opening at the bottom of each jamb. The hole is surrounded by the wooden panel which can be removed to reveal the inside workings.
Once you have the sash stopped and the access panel removed, you'll be able to take off the old sash weight and replace it with the new. Be sure to weigh the sash prior to you begin, as the old weights may be different in size from the one you need. After the new weight is installed, tie a string to it and thread it through the pulley of the sash. Then attach the string to the frame, but leave a few inches of string sticking out from the head to allow for future adjustments.
Sash Cords
In the majority of double-hung windows, a cord or chain is affixed to the weights. This keeps the sashes of the jamb level. Over time, these cords could break, making it difficult to raise the window. A new sash cable will restore the ability to move and lower the sash and keep it in place when it is opened.
To replace sash cords the first step is to remove the access panels from the jambs. These are usually attached by nails or screws and require removal. It may be possible to remove them using a hammer or chisel, however, it is best to lay out dust sheets before starting any work.
After the access panel has been removed, you can start working on the sash. Take the narrow beads (also known as "tie rails") out of their grooves using the chisel or flat bar. It is essential to take your time because they are usually wedged or nailed in place. If the sash is still in place, break the mortise and the tenon joints by using the help of a hammer and pin or screwdriver, then remove the wood pegs that are on each piece. It should now be possible to move the sash back and forth without difficulty, though it might require oil if it feels stiff.
With the sash in an open position Take a measurement of the sash chain to reach from the pulley at the top of the jamb to the sash slot in the bottom. Cut upvc window repairs or chain and attach it in the previous step. You can do this with a hammer, nails, or screws. However nails are less likely than screws to cause damage.
If you don't have an upgrade kit to replace the counterbalance system that was in place before, it is recommended to keep the original balancing weights in place. They're not expensive and simple to install if you purchase them at architectural salvage stores. Based on the dimensions and shape of your window, you may require one or two sashweights to keep it open.
